3 carb set up in my 280zx

[nismo 03]

i picked up a 3 carb set up from a friend for a few dollars and am now working on cleaning it up and replacing a few old parts on it

this is what my old set up looked like

this is what the carbs looked like when i first got them









Cleaning had started









thats the old carb



out with the old in with the new lol

oh wow! you had a home made single downdraft adapter, that could not have been efficient, you're gonna soo a huge power gain, gonna feel like a shot of NO2 when the secondaries open up

not really the single carb was great i rebuilt it from the ground up (new floater, gaskets, injectors, needles, etc....) and it was set up for a 2.8

but yes i should be getting a lil more power out of it

WTF! You had a single Weber DGV carb? That seems pretty crazy to me. But those new ones should be pretty awesome now.

yes i had one and it kicked a$$ + the car had no muffler or cat so it sounded real nice (sounds like a muscle car and shakes like one too lol) now am looking for son=me headers to go with the 3 carb set up and one of these

the header can be had from MSA for pretty cheap, the nissan motorsport ones cost more but I hear they flow better, as for the surge tank, they are rare, much easier to just make one, this company sells all the parts needed to make you're own http://www.rossmachineracing.com/products.html

yeah am thinking of calling some people i know to see if they can help out am not going to need it for the turbo any more i just need it to run a cold air intake thanks for the link!! i will take a look at what they have and for what price.

a man i really need to know more about the fuel set up can u help with that???

i know i need a FPR, some steel braided hose, electric fuel pump, any other thing ??? I dont know exactly whats better or were to start looking ill try hybridz but just dont want to go with the trial and error thing.

[evildky]

you don't need braided steel fuel lines, you won't be running very much pressure, you said you already had a low pressure electric pump? if not get one, then you just need a low pressure regulator, the webbers do not require a return you just have to keep the fuel pressure low enough to not defeat the needle valves and you're done

[nismo 03]

okay now let me ask one thing if i get a stock fuel pump and run a fpr would that work also???

i really hate the set up on the car the pump make a retarded sound when ever fuel is low lol

[evildky]

the stock electric fuel pump is high pressure, it would over power the needle valves and send gash shooting out of the fuel bowl vents, holley red is a good low pressure high volume fuel pump, enough fuel for way more hp than an L6 is gonna make an low enough pressure to not overpower the needle valves

got it.

people keep telling me that i am only suppose to run 4psi to the webers if i get an adjustable fpr (the one i had on my 240 came with a vacuume plug) will it be 4psi with or with out vacuume. or am i looking at a completely differen set up for the carbs?

[evildky]

the one off your 240sx was a high prssure model, you need low pressure, something like this http://store.summitracing.com/...w=sku the great thing is they tend to cost less tahn high pressure units
